My Take
I think this is a great tool for math classes. The graphing calculator allows students to visualize any function they are working with and compare multiple functions on the same screen. There are multiple calculators available and a space to construct and transform geometric figures. The Desmos online curriculum provides four grades worth of activities that show applications of concepts with engaging visuals. These also allow students to compare their reasoning to their classmates' after submitting certain answers.
How I Use It
This could be used to show students visual representations of the math concepts they are learning. The graphing calculator can be used by students to check their work with equations.
